Sarin, allegedly used by the Syrian regime to kill more than 1,400 people on Aug. 21, is one of the most toxic and rapidly acting nerve agents. Developed in 1938 by Germany as a pesticide, sarin is, in its pure form, a clear, colourless, tasteless liquid that has no odour. Even at low concentrations, sarin can be fatal within one minute and those who survive will have permanent neurological damage.
